2015 PORSCHE 911 CARRERA 4S four wheel drive

Principle 37
F o r 911 fans it ’s a question of faith, for
tech lovers it ’s an issue of performance:
rear or all-wheel drive?
The answer may turn out differently on
either side, but neither would be wrong.
Those who recognise the rear-driven
variant as being the one true 911
should
consider that the all-wheel drive setup
goes back to the legendary Paris–Dakar
Rally of 1984, when the Porsche 953
based on the 911
wrote its own chapter
in sport – and engineering – history. Fun
in the corners, by the way, is guaranteed
by both drive layouts. Two irreconcilable philosophies? Let’s
discuss a third: the design. The all-wheel
drive 911
models have a 44 mm wider
body, let ting it rest more firmly on the
road. An impression underlined by the
new light strip, especially after dark.
Another hallmark of the all-wheel drive
models: sheer supremacy. In every
corner and at any time of year. Porsche
Traction Management (PTM), the active
all-wheel drive system, varies the drive
force transmit ted to all four wheels as
the situation demands. This helps to
ensure solid roadholding and even bet ter performance. Simultaneously, of course.
In winter. Day in, day out. At the limits of
dynamic driving performance.
Fair-weather cars? The new 911
Ta r g a 4

models are any thing but. Here, the all-
wheel drive marries excellent traction
with excellent aesthetics.
Rear or all-wheel drive? Whatever stance
you take, the most fascinating philosophy
of life is and shall remain the practical
one. At Porsche, this philosophy has been
about the road for well over 60 years.
Even philosophical questions
can be answered with outstanding performance.
Rear-wheel and all-wheel drive.

Drive 51
The essential feature of all 911 all-wheel
drive models: enhanced Porsche Traction
Management (PTM).
Derived from the 911
 Turbo, the
electronically controlled and fully variable
multi-plate clutch distributes drive force
between the permanently driven rear
axle and the front axle even faster and
more precisely than ever before.
The driving state of the vehicle is
continuously monitored so that it is
possible to respond to different driving
situations. Sensors are used to collect a
range of data, including the rotational speed of all four wheels, the lateral and
longitudinal acceleration of the car and
the current steering angle.
If, for example, the rear wheels threaten
to spin under acceleration, a greater
proportion of drive force is transmit ted
to the front by a more powerful
engagement of the multi-plate clutch.
In this way, PTM, working in conjunction
with Porsche Stabilit y Management
(PSM), always ensures the appropriate
distribution of force necessary for
excellent driving performance and
particularly well-balanced handling at

the limit.

Chassis 63
SPORT button.
The SPORT button enables you to select
a suspension setup where the emphasis
is on either comfort or sport y performance.
At the push of a button, the electronic
engine management system switches the
engine mapping to offer an even sharper
response and engine dynamics that are
more direct.
In vehicles with Porsche Doppelkupplung
(PDK), upshifts take place at higher engine
speeds and downshifts happen sooner.
In addition, coasting mode and the auto
start/stop function are automatically
deactivated. If fitted, the optional sports
exhaust system is also activated
automatically.
Sport Chrono Package.
Adrenaline at the push of a but ton, goose
bumps included: the functions of the
optional Sport Chrono Package enable
an even sportier tuning of the chassis,
engine and transmission – and launch
you to unprecedented sporty heights.
What ’s new is the mode switch on the
steering wheel, derived from the
918 Spyder to make you feel closer to
the racetrack. Without your hand leaving
the steering wheel, you can choose any
of four set tings: Normal, SPORT, SPORT
PLUS and Individual. Now you can adapt
the vehicle even more to the way you
want to drive. On activation of SPORT PLUS mode,
Porsche Active Suspension Management
(PASM) and, in the S models, optional
Porsche Dynamic Chassis Control (PDCC)
and optional rear-axle steering adapt for
enhanced roadholding performance by
switching to a sportier damper set ting
and offering more direct turn-in on
entering the corner.
In combination with PDK, the Sport
Chrono Package has three additional
functions. The first is ‘Launch Control’,
which can be used to achieve the best
possible standing start – a racing start.
The second function is the motorsport-
derived gearshift strategy. In this mode,
Another few seconds faster.
Under the skin.
High-performance systems.
PDK is geared up for extremely short
shift times and optimum shift points for
the maximum acceleration available.
This combination of uncompromising and
involving performance is ideal for the
racetrack.
The third function – SPORT Response –
is brand new to the 911. Pressing the
but ton in the centre of the mode switch
primes the engine and transmission for the
fastest possible unleashing of power. In
other words, maximum responsiveness –
for a period of approximately 20 seconds.

tells you how long is left.

Adaptive cruise control including
Porsche Active Safe (PAS).
Available as an option in conjunction
with Porsche Doppelkupplung (PDK),
this enhanced version of cruise control
actively regulates the speed of your
vehicle in line with the speed of the
vehicle in front. A radar sensor scans the
road ahead up to a distance of 200  m.
If Porsche Active Safe (PAS) detects that
your vehicle is approaching the vehicle in
front too quickly, the system issues an
audible and a visual warning. Where
necessary, this may be accompanied by
a brief jolt of the brakes and the initiation
of targeted braking. During this process,
any braking by the driver is boosted to
achieve the maximum braking force that
the system is able to provide. With the new 911, coasting is now
possible even while adaptive cruise
control is active.
Lane Change Assist.
New Lane Change Assist, available as an
option, uses radar sensors to monitor
the areas to the rear of the vehicle and
the blind spots on either side. Above a
speed of 9 mph, the system issues a
visual warning signal in the door mirror
panel whenever a vehicle rapidly
approaches your vehicle from behind

or enters one of your blind spots. In
this way, Lane Change Assist improves
comfort and safety, particularly on
motorways. However, the system does
not actively intervene to control the
vehicle and can be deactivated at any
time.
ParkAssist.
Featuring four inconspicuous sensors in
the rear end, the system audibly alerts
the driver to the presence of obstacles
detected behind the vehicle. An
intermittent warning tone increases in
rapidit y as the obstacle is approached.
ParkAssist can be optionally upgraded to
include monitoring of the front end with
four additional sensors. The audible alert
is supplemented by a visual warning in
the central display screen, which shows
a graphical representation of the vehicle
from overhead.
The optional reversing camera facilitates
precise reverse parking and manoeuvring.
Help is provided in the form of the camera

image and the dynamic, superimposed

guidelines on the PCM screen, which

Speed limit indicator.
The camera-based speed limit indicator
informs you of speed restrictions and

instrument cluster and on the screen of
